◆
The leak rate should be less than 0.02mbar/s for ADT761-D and 0.2bar/s for ADT761-L and ADT761-M or it is
possible the calibrator has a leak.
◆
The ADT761 can also run an automatic leak test (as shown in Section 3.6.1).
4.4 Instability
If the pressure has been unstable for more than 3 minutes in the CONTROL mode, the calibrator will switch to the
STANDBY mode and check for the following:
◆
Make sure all fittings are tightened (Section 3.4.1).
◆
Investigate the system for any potential leaks.
